Mechanism of secretion of adenylate cyclase toxin from Bordetella pertussis via Type I secretion system (TISS)
Klímová, Nela ; Bumba, Ladislav (advisor) ; Konopásek, Ivo (referee)
Type I secretion system in Gram-negative bacteria translocates proteins from the cytoplasm to the extracellular medium in a single step across both membranes. The membrane-spanning channel is made up of just three proteins - an ATPase in the inner membrane, a membrane fusion protein and a specific outer membrane protein. This work provides a summary of current knowledge concerning the structure of the secretion system, as well as the assembly of the trans-envelope complex and the mechanism of protein secretion. The role of substrate folding on secretion is highlighted. It deals to some extent with the properties of the substrates translocated by the type I secretion system, with emphasis on the adenylate cyclase toxin of Bordetella pertusis, the agent causing whooping cough.
